Just in case you forgot what cold weather feels like, the next couple of days will be a cold slap in the face.
But, incredibly, not only will the cold be short-lived, but we will actually transition by next week to a very warm pattern, with temperatures by mid-week reaching the 60s and maybe even near or above 70 degrees!
Some medium range models continue the roller-coaster ride by mid-month, with a colder, stormier pattern taking hold. While highly unreliable during this time frame, the GFS model has persistently shown some sort of east coast storm system in the January 14-18 time frame.
So winter is here, winter will leave, but winter will come again!
